Tooth Discoloration: Causes, Types, Treatments, and Prevention Tips
Tooth discoloration refers to a change in the natural color of your teeth, often resulting in a duller smile. This condition can be caused by external staining or changes within the tooth structure. Knowing its causes and treatments can help address it effectively.
What Is Tooth Discoloration?
Teeth become discolored when there is a noticeable color change in them. It might be extrinsic, where discoloration involves surface stains and it is relatively simpler to treat; or intrinsic changes within the tooth structure of the teeth may require more severe intervention procedures.
Causes of Tooth Discoloration
Tooth discoloration might be due to several causes and can be differentiated into the following broad categories.
Extrinsic Causes or Surface Staining
- Food and Beverages: Drinks such as coffee, tea, red wine, and cola are the most common causes of stains on the outer layer of the teeth. Tobacco use can also cause surface stains.
- Plaque and Tartar Build-up: Plaque is a sticky film that develops on the teeth. If it is not cleaned properly, it hardens into tartar. Tartar, over time, can stain, absorbing pigments from food and drink.
Intrinsic Causes (Internal Discoloration)
- Aging: Aging naturally wears down the enamel, exposing the yellowish dentin underneath. This exposes the yellow dentine inner core.
- Health Conditions and Medications: Certain antibiotics such as tetracycline and too much fluoride during child development can cause inner stains. Moreover, injuries or decay in the inner tooth structure cause discoloration.
- Poor Oral Hygiene: Failure to brush and floss usually leads to plaque that eventually gives way to tartar and discolors the tooth.
Types of Tooth Discoloration
There are two main types of tooth discoloration:
- Extrinsic Stains: These involve stain appearing on the enamel of the teeth, caused by external sources such as food, beverages, or smoking. Such extrinsic stains can be usually removed through whitening products or professional cleanings.
- Intrinsic Stains: These affect the inner tooth structure and can be caused by factors such as aging, trauma, or certain medications. Intrinsic stains are more difficult to treat and may require solutions like bleaching or veneers.

Treatment for Tooth Discoloration
The treatment for tooth discoloration depends on the type and cause of the discoloration:
- Whitening Treatments: These involve whitening agents, such as whitening toothpaste, and professional whitening treatments at the dentist’s clinic. They may be very effective for extrinsic stains.
- Dental Veneers: Intrinsic stains cannot be removed effectively by whitening treatments, for which dental veneers are recommended. These are ultra-thin layers of porcelain bonded to the tooth surface that mask discolouration.
- Regular cleanings: This helps prevent the buildup of plaque and tartar in the mouth. A professional cleaning can remove surface stains and prevent further discoloration.
- Avoiding staining foods: Reducing the consumption of staining foods and drinks, such as coffee and tea, can help keep the teeth whiter.
If you experience tooth discolouration, take a visit to the dentist before deciding on appropriate treatment for the condition. Tooth discolouration can be treated according to the dentist’s advice suitable for your mouth.
